the larger pipe can carry twice the volume of the two smaller pipes
the cross sectional area is proportional to the square of the radius
smaller pipes ... 2 * (π * 2^2) = 8 π
larger pipe ... π * 4^2 = 16 π
Which pipe configuration can deliver more water to presidents one 8 cm pipe or two 4cm pipes? Show your work and explain your reasoning.
